While most YouTube videos are typically between around five minutes and half an hour, there are plenty that can stretch well beyond that depending on the topic they're covering.
Many vlog channels, for example, regularly share videos that are over an hour long, and you also have the growing popularity of video essays that stretch several hours in length — almost longer than some TV shows in extreme cases.
That's not even counting the various videos deliberately designed to extend for longer than you need, like themed music collections, fireplace videos that have earned a surprising amount of money, and even a new trend that sees AI-generated videos designed to help people fall asleep.

One newly uploaded video takes the cake by a considerable margin when it comes to pure length though, and it's sheer scale has left everyone who clicks on it confused and baffled at how exactly it has been uploaded.
As shared by Dexerto, the video in question seemingly stretches 140 years in length despite only featuring a blank screen. Uploaded by 'shinywr', the video simply has a question mark icon for its title, accurately summing up the situation surrounding its existence.
Looking at the channel page you can see that its length is listed as '1,234,567:30:00', which equates to just under 141 years in total — although it could potentially be even longer than this considering the ascending nature of this figure, suggesting that it's reached the limit of what YouTube can display.
Clicking on the video itself, however, you can see that only 12 hours, 34 minutes, and 56 seconds of that 140-year total length is visible and playable, and the video simply stops when you reach this point.

YouTube's internal upload limit appears to be 12 hours, with a file size cap of 128gb, and despite featuring no image whatsoever, it's almost guaranteed that a video this long would go well beyond that fixed ceiling.
"So we're all here on a random Saturday," jokingly questions one comment underneath the video, yet if you were to watch the whole thing with no speed adjustments from this very moment, you'd finish it in time for around December 18, 2166.
"Gonna report this for nudity so that YouTube has to watch the whole thing," jokes another user, with a third predicting that "this is gonna have some insane lore in 10 years."

That's not the only lengthy video on the channel either, as there's also a 294-hour-long video that was uploaded two months ago, alongside an oxymoronic Short that somehow lasts 150 hours.
